Definitions

  • the invention relates to multi-jet water meters according to the preamble of claim 1.
  • Water meters with measuring inserts which can be adjusted independently of the metallic meter housing and which are to maintain their correct adjustment when installed in any housing are known, for example, from DE-A-22 05 154, DE-A-29 23 628, DE-A-23 37 465, DE-A-23 38 327, DE-B-12 40 677, DE-B-23 39 897, DE-B-11 60 200, DE-B-10 19 835 or DE-U-73 11 732 .
  • the complete meter housing usually made of cast brass, is replaced with the old measuring insert and returned to the manufacturer.
  • the old measuring insert is removed, the metal housing is cleaned, a new measuring insert is inserted, the complete unit is adjusted and finally the certification stamp is attached.
  • the water meter according to the invention has, as an essential element, a measuring insert with a plastic housing, which can be inserted into the actual metal meter housing.
  • the plastic housing called cartridge, contains all the components that are required for calibration.
  • the use also guarantees functions of the previous meter housings, for example the pressure-tight seal to the outside, the unobstructed view of the measuring mechanism, etc.
  • the measuring insert is considerably lighter and smaller than the metal meter housing. Storage and transportation are simplified. In the future, the metallic meter housings can remain in the pipeline when the measuring insert is replaced; any deposits are simply wiped off.
  • the water inlet and outlet are coaxial to each other in the bottom of the cartridge housing.
  • the measuring insert can be inserted from above into the lower part of the metal housing and fastened by means of a head screw connection, the sealing between the water inlet and outlet being effected by the axial pressure on an O-ring inserted into an annular hub in the bottom of the lower part of the cartridge.
  • Axial tolerances are compensated for thanks to the resilient property of the bottom of the lower part of the cartridge.
  • the cartridge housing consists of at least two parts, the lower part of the cartridge and the upper part of the cartridge. Both are due to a non-destructive connection connected with each other.
  • this can be a snap-in connection with a circumferential snap-in groove and snap-in spring.
  • the lower part of the cartridge and the upper part of the cartridge advantageously have corresponding centering cams and centering grooves. This ensures that the two cartridge parts are installed at the correct angle.
  • the wing cup consists of a wing cup lower part and a wing cup upper part produced separately therefrom, which are mounted at the correct angle with the aid of adjusting pins and corresponding adjusting holes in the mutually facing separating surfaces. If the adjustment pins are correctly dimensioned in relation to the adjustment holes, it is possible to connect the lower and upper parts of the wing cup to one another by welding.
  • the tangential inflow channels are only provided in the wall of the wing cup upper part. There are preferably two three inflow channels, which are arranged opposite one another. In order to influence the flow characteristics, hydraulic internals in the form of radial stowage ribs, a circumferential stowage edge and stowage spaces are provided in the inner wall of the wing cup.
  • the apron is also to be included in the hydraulic installations, with a certain amount in front of the inflow ducts Distance to these is arranged, the inlet channels partially covered and has an approximately parabolically curved inner surface.
  • Water meters are equipped with a hinged protective cover, which protects the transparent top from dirt and damage.
  • this foldable protective cover is articulated directly on the upper side of the upper part of the cartridge, preferably by means of an articulated pin which is inserted into a blind hole. Thanks to this type of installation, the protective cover cannot be removed without visible destruction. This in turn makes it possible to affix certification stamps, manufacturer's marks etc. directly in the protective cover.
  • the meter housing can be made very simple. It consists of a lower part with a coaxial arrangement of water inflow and outflow and an upper part as a screwed head. Sealing against the escape of water takes place using only three O-rings, one for the seal between the lower part of the housing and the upper part of the housing, one for the seal between the lower part of the housing and the cartridge and one for the seal between the cartridge and the screwed head.
  • a check valve preventing backflow can be inserted into the lower part of the meter housing, advantageously directly under the cartridge.
  • This check valve can be used when installing the measuring cartridge and can also be replaced when the measuring cartridge is replaced.
  • Annular gaps are provided, for example where the impeller shaft in the wet rotor type passes through the wing cup or the counter, or where the measuring cartridge is accommodated in the lower housing part. These ring gaps should prevent water flow as far as possible without hindering the pressure equalization.
  • the lower part of the cartridge tapers slightly conically towards the bottom. This leaves a conical gap between the housing and the measuring cartridge, which minimizes the water exchange and thus the deposits, so that later replacement or replacement of the measuring cartridge is possible without problems.
  • the measuring insert can be designed not only as a wet runner but also as a dry runner.
  • the wing cup is supported at the top with a pressure-resistant metal plate, the speed of the impeller is transferred to the counter in a known manner by means of a magnetic coupling.
  • Fig. 1 shows a longitudinal section through a measuring cartridge 3 of the wet rotor type.
  • a cup-shaped, slightly conical lower cartridge part 30 and a pressure-resistant upper cartridge part 31 made of transparent plastic material can be seen, which are non-releasably locked together by means of a circumferential tongue and groove connection 34.
  • An adjusting cam 35 in a corresponding groove ensures the correct angular position of lower cartridge part 30 and upper cartridge part 31.
  • a protective cover 32 is fastened in a blind hole by means of a hinge pin 33. Thanks to this permanent attachment of the hinged cover 32, it is possible to affix the manufacturer's mark, certification stamp 32 ', etc. on the inside of the hinged cover 32.
  • permanent attachment means that the parts cannot be separated from one another without visible damage.
  • the lower cartridge part 30 has a bottom, the outer annular surface 38 of which is designed as a dirt screen.
  • the sieve openings are slightly conical. This will make the water accelerated when passing through; the resulting pressure drop causes any impurities to fail before they get inside the measuring cartridge 3.
  • a hub ring 37 can be seen, in the underside of which an O-ring 14 is inserted, which seals the meter housing 1 (FIG. 5).
  • the lower edge of the lower cartridge part 30 is tapered in steps and provided with adjusting cams 39 which ensure the angular positioning of the measuring cartridge 3 in the meter housing 1.
  • a wing cup consisting of a lower wing part 40 and a upper wing cup 60 can be seen below, in which, in a manner known per se, an impeller 42 rotates on a bearing tip 41 so that it can rotate easily.
  • An impeller shaft 43 is guided through the upper part 60 of the cup and drives a reduction gear 75 seated in a measuring cup 70.
  • annular gaps 67 and 67.1 are formed which seal like a labyrinth against water currents without preventing the water from entering the measuring cup. This measure prevents harmful deposits in the counter from the water flowing through.
  • the measuring cup 70 is essentially formed by a cylindrical plastic ring, placed on the wing cup upper part 60 and covered by a dial 72 at the top. There are pointers 73 and number rollers 74 arranged so that they can be easily read through the cartridge upper part 31.
  • an apron 65 is integrally formed on the upper wing cup part 60 and at a distance from the tangential inflow channels 61. Their inner side facing the inflow channels 61 is curved approximately parabolically. This has a favorable influence on the deflection of the measuring water, which initially rises vertically, into the horizontal.
  • the lower edge of the apron 65 sits on a step 36 on the inside of the lower cartridge part 30, as a result of which the wing cup 40, 60 is correctly positioned.
  • Adjusting cams 66 on the underside of the apron 65 ensure the correct angular position.
  • the wing cup lower part 40 has two bypass openings 44 at the bottom, with which the display can be moved to minus or plus.
  • an adjustment ring 50 is inserted into the central water outlet opening in the bottom of the lower cartridge part 30. Its upper edge 51 is double ramp-shaped and closes a more or less large part of the adjustment openings 44 depending on the angular position of the adjustment ring 50.
  • FIG 3 shows a plan view of the lower wing part 40, a part of the upper wing part 60 being visible in section.
  • the impeller 42 and its cut shaft 43 can be seen radial retaining ribs 45, which are inclined in the area of the central water outlet opening 46, in order to cause the impeller 42 to reverse in the event of a backflow of water.
  • the baffle ribs 45 serve to influence the water flow so that the measurement accuracy is improved.
  • FIG. 3 also shows adjustment pins 47 on the lower wing part 40, which are inserted into corresponding bores in the upper wing part 60. This ensures that the wing cups 40, 60 are mounted at the correct angle.
  • FIG. 4 shows the view from below into the wing cup upper part 60.
  • Radial stowage ribs 62 and a peripheral stowage edge 64 can also be seen on the ceiling of the wing cup upper part 60.
  • three tangential inflow channels 61 are provided twice.
  • the apron 65 with adjusting cams 66 can be seen on the outside of the wing cup upper part 60 at a certain distance from the inflow channels 61 and partially covering them.
  • the apron 65 with its approximately parabolically curved inside, the stowage edge 64, the storage ribs 62, 45 and the storage spaces 63 are responsible for the meter shown measuring the water with the accuracy of the metrological class C.
  • FIG. 5 shows a longitudinal section through the meter housing 1 with the measuring cartridge 3 mounted according to FIGS. 1 to 4.
  • the meter housing 1 has a water inlet connector 11 and a water outlet connector 12. The separation between the water inlet and outlet takes place through an annular surface 13 on which the O-ring 14 in the underside of the measuring cartridge 3 sits on.
  • the measuring cartridge 3 is fastened in the interior of the meter housing 1 by means of the head screw connection 15 and sealed with O-rings 16 and 17.
  • a seal 18 protects against unauthorized manipulation.
  • the lower cartridge part 30 is slightly tapered towards the bottom 38. This leaves a gap 19 between the measuring cartridge 3 and the meter housing 1, in which dirt particles can be deposited from the water without impeding the removal of the measuring cartridge 3.
  • annular gaps between the measuring cartridge 3 and meter housing 1 or head screw connection 15 it is also ensured that as far as possible no water can flow through these housing areas.
  • a check valve 20 with a valve seat 21 preventing the backflow of water can be inserted into the meter housing 1 directly under the measuring cartridge 3. If the measuring cartridge 3 is replaced on site after the calibration validity period, and, as already mentioned, only the head screw connection 15 is loosened while the lower housing part 1 remains installed in the line, the check valve 20, 21 can also be conveniently replaced from above.
  • FIG. 6 shows a longitudinal section through a meter housing 1, into which a measuring cartridge 3 of the dry-running type is inserted is.
  • a pressure-resistant metal plate 600 can be seen, which covers the upper part of the wing cup 60 in a pressure-tight manner at the top.
  • a magnetic coupling 601 is provided to transmit the speed of the impeller to the measuring mechanism. Otherwise, the construction of the meter housing 1 and the measuring cartridge 3 consisting predominantly of plastic is identical to the measuring cartridge of the wet-running type of FIGS. 1 to 5.
  • the desired measuring cartridge 3 which is capable of being calibrated and transported, is present and bears the stamp 32 'of the manufacturer's works.
  • the fitters of the water supply companies only have to carry this light measuring cartridge 3, which consists essentially of plastic.
  • the head screw connection 15 is loosened, the old measuring cartridge 3 removed, if necessary also the check valve 20, any deposits in the meter housing 1 wiped out, a new measuring cartridge 3 and, if appropriate, a new check valve 20 inserted, the head screw connection 15 screwed on again to the stop and the security seal 18 attached.
  • the old measuring cartridge no longer has to be returned to the manufacturing plant, but is disposed of properly as plastic scrap.
